Excerpt from Notes on the Graphics of Machine Forces

In section I are added some special force constructions which are useful chiefly in the problems of graphical dynamics, but which are needed to round out the presentation of graphical methods for determining impressed forces in machines.

It is thought that the title here used is more appropriate and descriptive than graphical statics of mechanisms.

Excerpt from Notes on the Graphics of Machine Forces

1. In order to determine, by the simpler methods of graphical analysis, the principal forces acting in machines, we make the following assumptions:

(a) The weight of the machine members, or the force of gravity acting upon them, may be disregarded.

(b) The force of inertia need not be taken into account: this idea involves either a slow running of the machine or a practically uniform motion of the parts.

A great many problems may be solved with quite sufficient correctness under these assumptions. If the need of greater accuracy or their increase in relative magnitude requires that these forces (which are functions of mass or of mass and motion) be included, the solution becomes much more complicated. (See Section J.)

2. For present purposes, the machine is considered as made up of rigid bodies, or of members which are fixed and definite in form so far as the forces entering into the problem are concerned. These are all impressed forces, imposed through the contact of one machine part with another. The forces which act upon one piece get at each other and come into equilibrium through the medium of internal forces or stresses within the body. We pass over all questions as to the magnitude or the manner of action of these stresses, and use simply the resultant relations among the imposed forces; which relations are the same as if the forces acted upon and met in a single material particle.
